Get iModel Named Versions - iModels

iModels

Download API definition:

GET https://api.bentley.com/imodels/{id}/namedversions[?$top][&$skip][&$orderBy][&$search][&name]

Retrieves a list of Named Versions for the iModel specified by the iModel id.

Every Changeset on the timeline creates a new version of the iModel. However, some points on the timeline can represent important milestones or significant events to be saved. iModelHub provides a way to mark a point on the timeline with a name. These time points are referred to as Named Versions.

Notes

The Prefer header can be used to specify how much result metadata is desired by the client. The Prefer request header field is used to indicate that particular server behaviors are preferred by the client but are not required for successful completion of the request.

This operation supports "return=representation" and "return=minimal" preferences.

The "return=representation" preference indicates that the client prefers that the server include an entity representing the current state of the resource in the response to a successful request. The "return=minimal" preference indicates that the client wishes the server to return only a minimal response to a successful request. This is the default preference if Prefer header is not specified.

Authentication

Requires Authorization header with valid Bearer token for scope itwin-platform.

For more documentation on authorization and how to get access token visit OAUTH2 Authorization page.

Authorization

User must have imodels_webview permission assigned at the iModel level. If iModel Role permissions at the iModel level are configured, then user must additionally have at least imodels_webview permission assigned at the iTwin level. If permissions at the iModel level are not configured, then user must have imodels_webview permission assigned at the iTwin level.

Alternatively the user should be an Organization Administrator for the Organization that owns a given iTwin the iModel belongs to.

For more information please refer to Account Administrator documentation section on Access Control API documentation page.

Rate limits

All iTwin Platform API operations have a rate limit. For more documentation on that visit Rate limits and quotas page.

Request

Request parameters

Yes

iModel id

$top

The $top query option requests the number of items in the queried collection to be included in the result. E.g. to return only first collection item provide the following query: $top=1. When $top parameter is not provided default is set to 100. $top value cannot exceed 1000.

$skip

The $skip query option requests the number of items in the queried collection that are to be skipped and not included in the result. E.g. to return items from the collection starting at the third place provide the following query: $skip=2.

$orderBy

The $orderBy query option allows clients to request ascending using 'asc' or descending using 'desc' order of the returned collection by one or more item properties. Currently supported properties for Named Versions are 'changesetIndex' and 'createdDateTime'. When neither 'asc' or 'desc' keyword is specified the collection is sorted in ascending order. To sort the collection in descending order provide 'desc' keyword e.g.: $orderBy=changesetIndex desc,createdDateTime desc

$search

The $search query option allows users to filter Named Versions whose name or description property contains the search string. E.g. to return Named Versions whose name or description contains 'Milestone 1', provide the following query: $search=Milestone%201. This parameter cannot be used at the same time as the name parameter. Valid values for this parameter are non-empty strings that are not longer than 255 characters.

name

The name query option allows users to filter Named Versions by their name property. E.g. to return Named Versions that have a name equal to 'Milestone 1' provide the following query: name=Milestone%201. Valid values for this parameter follow the same requirements as for Named Version creation - strings should be not empty, consist not only of whitespace and not exceed 255 characters. This query option uses case insensitive matching.
